Free browser tools I've been building for U1 multicolor (converter, photo→3MF, painter)

Some of you have already used U1 Forge from the converter thread. I’ve been building a few more browser tools to make multicolor on the U1 easier, so I figured I’d put them in one place. All of them run in the browser, nothing to install, and they’re free to start.

U1 Forge — drop a Bambu/Prusa/MakerWorld .3mf and get a U1-ready file with the color painting kept intact. New this week: it also carries your print settings over (layer height, infill, walls, speeds, temps), so you don’t have to open the file in Bambu Studio first just to move settings. https://inkwell.wiki/u1-forge

Spectrum Forge — turn a photo into a multicolor / HueForge-style .3mf. Pick a palette, set your layers and size, export, then open it in Snapmaker Orca as a project with the colors already baked in. https://inkwell.wiki/spectrum-forge

Paint Forge — project a photo’s colors onto a model you already have and paint it for multicolor, with the inner-wall filament swaps handled for you. https://shapedqr.com/forge

On cost so nobody’s surprised: there’s a free monthly allowance you can use without even giving an email, and signing up adds 50 free credits you keep. The same wallet works across all three, and you only pay if you’re running a lot through them.

These all came out of my own U1 printing headaches, so I’d really like feedback from people actually printing multicolor here — what’s still painful, and what should I build next?

Hi, we’ve actually had a similar converter shared by one of our community members before:https://bl2u1.nbn.cat/

As for turning photos into full-color 3D prints, Lumina Studio already seems to have made that happen:

So I’m curious — what advantages would your tools offer compared to the Lumina approach?
